We’ve answered calls at 2 a.m. in snow so thick we couldn’t see ten feet ahead. Doesn’t matter. If your rig’s down in Oak Ridge, we’re on the move: rain, shine, sleet, or black ice. Our mobile diesel repair units hit the road fully stocked and ready for the real problems: brake failures, air leaks, regens that won’t quit, and electrical gremlins that leave you dead on the shoulder.
For the heavy jobs, like engine failures, blown turbos, or suspension collapses, we tow the truck straight to our Dale Road facility near Oak Ridge. The bays there can take in tankers, vocational rigs, and long-haul tractors without delay. From teardown to rebuild, every step happens in-house. The goal stays the same through every shift: get the truck running and the driver back behind the wheel.

Drivers out of Oak Ridge and the surrounding areas call us because we show up with the proper setup: no waiting for a second truck, no guessing about parts. We’ve handled electrical shorts on Route 322, replaced axle seals in muddy job sites, and fixed air leaks behind warehouses where other repair trucks couldn’t even turn around. Every call gets the same focus: find the fault, fix it right there, and keep the driver’s schedule intact.
And our in-shop crew doesn’t guess. We diagnose, repair, and replace. Come to us with your problems regarding transmissions, suspensions, drivetrains, and exhaust systems. We know you don’t want promises. You want someone who shows up, gets dirty, and gets it done. That’s us. Call anytime, and we’ll either roll to you or be waiting when you roll in.
We don’t just handle the breakdown; we look at what caused it. Maybe your suspension’s been uneven for months, or your tires are wearing wrong because of an axle issue nobody flagged. We spot the things others miss because we take the time to check the whole rig, not just the problem you called about. That extra step? It’s how we help you avoid the next call.
Inside our Oak Ridge shop, there’s always something happening: sparks from a welding booth, the hum of a test run, the smell of diesel mixed with steel dust. That’s what 30 years of collision and mechanical work looks like. We can straighten bent frames, rebuild axles after jackknifes, and replace whole sections of bodywork after winter wrecks on Route 219. Our technicians handle insurance claims directly, keeping fleet managers updated through every stage so repairs don’t stall behind paperwork.
We also handle the paperwork that comes with it: insurance claims, estimates, and updates go straight to the dispatch office or fleet coordinator. Our goal is simple: communication as steady as the repairs. Thirty years in the business taught us that a quiet truck bay costs money, so we keep every stall filled and every job moving until the next rig pulls in.
Bigler Boyz keeps Oak Ridge’s heavy trucks rolling with a full lineup of hands-on, no-frills repairs. From drivability issues that leave no fault codes to full-blown breakdowns that stop you in your tracks, our crew handles it all. In the shop or on the side of I-80, we’re wrenching on what matters, not just clearing codes or guessing at fixes. Cooling systems that overheat in the hills, air brakes that start leaking after a rough load, electrical problems that knock out lights or kill your starter: we’ve seen it, fixed it, and moved on to the next call. Our approach is simple: fix it right, fix it fast, and don’t leave the driver hanging.
